Title: Method and device for grinding finishing of sheet ring valve stem hole in butterfly valve
Inventor: OSAKI MITSUO
IPC: B24B15/04
Filed: 1989-01-10
Abstract: PURPOSE:To improve dimensional accuracy and to shorten the necessary time, by uniformly grinding off the whole face of a work part by turning a fitting base with rotating a grinding and grinding off in the desired dimension by repeating the same procedures by advancing the fitting base in the orthogonal direction with a valve stem. CONSTITUTION:At the tip of a support arm 37 a grinder 15 is fitted and a grindstone 52 having the width T longer than the hole length H of a valve stem hole is fitted to the tip thereof. The grindstone 52 can be moved to the position coming into contact with the whole face of the sheet ring valve axial hole where the polishing face thereof is to be finished uniformly and yet can be fixed at the position thereof, so the whole face of the valve stem hole can be ground off uniformly in the specific depth, by executing one rotation by turning a fitting base 16 slowly with rotating the grindstone 52 at high speed. Moreover by repeating the same procedures by advancing the grindstone 52 deeper the hole whole face is ground off uniformly further by the depth part and the grind finishing can easily be performed precisely in the desired dimension.

Filed: 1990-01-10
Abstract: PURPOSE:To improve the after-image and the output characteristic by providing a bipolar transistor(TR) array with light shield near a bipolar TR array and connecting a reset switch to bases of the respective bipolar TRs. CONSTITUTION:Picture element selector switches 9, 13 of a bipolar TR 7 and a dummy bipolar TR 11 in pairs are turned on simultaneously and charges are outputted respectively to common signal lines 10, 14 from both the TRs 7, 11. The picture element selector switches 9, 3 are closed sequentially to output a picture signal and a dummy signal to the common signal lines 10, 14 in time series. After the output, base reset switches 8,12 are closed and then a base level of the bipolar TRs 7, 11 reaches VB. Since the bases of the bipolar TRs 7, 11 are reset for each time to the voltage VB, the effect of a preceding output is not left and no after-image takes place.

IPC: H03K17/567
Filed: 1993-01-12
Abstract: PURPOSE:To suppress the fluctuation of an H output level, and to limit the interaction of a time constant circuit only at the time of holding the H output by stabilizing the base potential of an H output side transistor to the averaged voltage of the time constant circuit. CONSTITUTION:This circuit is equipped with a time constant circuit 6 which outputs the averaged voltage Va of a power supply voltage Vcc-Vss by a resistor R1 and a capacitor C1, and a switch circuit S1 which is on and off controlled by an H output holding signal DOEH. Then, the base of an H output side transistor TrQ1 is connected to the voltage Va of the circuit 6 through the circuit S1. Therefore, the fluctuation in the H output level can be suppressed by stabilizing the base potential of the Tr Q1 by these additional circuit in spite of the fluctuation of the power supply voltage due to the circuit 6. Also, the interaction of the circuit 6 is limited only at the time of holding the H output by the circuit S1. Thus, the fluctuation of the output level due to a power source superimposed noise such as a reset noise can be suppressed without interfering, the acceleration of the outputting operation speed.

Abstract: PURPOSE:To prevent the generation of crosstalk by a simplified circuit by entering a pilot signal as a digital value of an A/D converter and detecting the peak level of a pilot signal from an adjacent track to find out a tracking error. CONSTITUTION:The pilot signal selected by a BPF 16 is synchronized with the pulse of a pilot conversion clock generator 17a and converted into a digital value by an A/D converter 17b. A peak level detector 18 detects the peak level of a digital pilot signal obtained from the adjacent track and sends the detected value to a storage circuit 19 by the output pulse of a pulse generator 15. A subtractor 20 subtracts the output signal of the circuit 18 from the output of the circuit 19 and sends the subtracted result to a storage circuit 21. The output of the circuit 21 is added to a value obtained by subtracting the values of a period calculator 4 and a reference value generator 10 by a subtractor 11 and controlled by a D/A converter 22 and a driver 13 so that the output data of the circuit 21 are turned to zero. Consequently, the heads 2a, 2b can travel on the center of a track to be recorded and crosstalk is not generated between tracks.
